Handheld magnetic probe to detect hook-wire inside the tissue

Abstract

Breast conserving surgery is a common surgery to treat localized breast cancer. Once the tissue is removed, it is sent to get an X-ray to check the margin. This process requires such set-up and radiology expert to do so. This research work proposes a method to detect the hook-wire by using a magnetometer. The magnetometer with a permanent magnet and hall sensor inside (Masaki Sekino et al, 2018) can be used to detect the location of the hook-wire having magnetic property. Normally this hook-wire makes different angels inside the tissue and considering the possibilities of different angles made by hook-wire, the calculation is done to detect the location of the hook-wire by this magnetometer which can detect magnetic particles in three-dimensional direction (Kuwahata et.al, 2017). Experimental data shows the magnetic sensitivity to be maximum when the asymmetry part faces the probe. Real surgery conditions would be considered in further experiments.
